Flower, who was known for his ‘urbane and hospitable disposition’, had a perfunctory parliamentary career as Conservative member for Thetford.
At the 1841 general election Flower accepted a requisition from local electors to stand for Thetford, a small borough about twelve miles west of Eccles Hall, whose electorate numbered just under 200.
A steady attender, Flower gave steadfast but silent support to the Conservative ministry on all major issues. He was especially loyal to Peel, for whom he hosted a Conservative dinner party at his London residence in August 1843.
With Thetford’s two dominant political families, the Barings and Fitzroys, keen to restore shared representation, Flower declined to stand for re-election at the 1847 dissolution.
